UNITED STATES JAMES B. L. BROWZT, 015 LOS ANGELES, CALIFORNIA.

BUMPER.

Application filed July 21, 1922.

To all whom z't may concern:

Be it known that 1, JAMES B. L. BROWN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Bumpers, of which the following is a specification.

My invention relates to spring bumpers, and particularly to automobile spring bumpers, and the main object of my invention is to provide an automobile bumper which may be made in one piece, or of a single bar of spring steel and secured directly to the end of the automobile chassis, thus eliminating the use of brackets or other parts which are necessary in mounting other bumpers on automobiles, and materially reducing the cost of bumpers.

T he invention has for further objects the provision of an improved bumper which will be superior in point of relative simplicity and inexpensiveness, taken in conjunction with utility, durability and general efliciency and serviceability.

With the above and other objects in View, the invention consists in the novel and useful provision, formation, construction, combination, association and inter-relation of parts, members and features, all disclosed in the accompanying drawing, described in the following statement, and finally pointed out in the claim.

In the drawing:

Figure 1 is a plan View of my bumper as applied to the front end of an automobile;

Figure 2 is a perspective view of my bumper as shown in Figure 1.

My bumper is made of a single bar 1 of spring steel, and comprises an impactreceiving member 2, connecting members 3 3 thrust members 1- and securing members i-*5. The connecting members connect the ends of the impact-receiving member 2 and the forward ends of the thrust members 4- l, and are formed by bending the bar 1 at 66 at the ends of the impact-receiving member inwardly, nearly parallel to said member at a short distance from the inside thereof, so that the connecting members extend at a slightly acute angle to the impact-receiving members. The thrust members l-l are formed by bending the bar inw rdly at from the inner ends of the connecting members 3-8 at obtuse angles Serial No. 576,570.

to said connecting members. The thrust men'ibers 4-4- of the front bumper shown in Figs. 1 and 2 extend at only slightly obtuse angles, or nearly at right angles to the connecting members and impact-receiving member 2 to resist great shock thereto, but

"The securings members of the front bumper are bent inwardly at 88 from the rear ends of said thrust members substantially at right angles to said thrust members and downv ardly angles therefrom, so that they may fit against the end portions of the front end. member 9 of an automobile chassis such as the Ford automobile ell-as sis, which end member is bent downwardly from its ends to form the saddle for the front spring of the automobile. The securing members 5-5 are apertured near their junc tures with the thrust members 4el to receive the forward ends of hook bolts 1010, which hook over the front lamp brackets 1111 extending outwardly from the sides of the chassis at the front endthereof. Nuts 12 12 screw on the front ends of said hook bolts against the securing members 5 5. U-bolt clamps 1313 extend over the front end chassis member 9 and over the securing members 55, whereby said securing members are clampedaq'ainst said chassis member. The hook bolts 1010 and clamps 13-13 detaehably secure the bumper directly on the front end of the automobile.

The impact spring action of the impactreceiving member 2 is limited by the engagement of said member with the connecting members 3 S at the points 77, whereupon the thrust of the impact is resisted.

directly by the thrust members l l. The thrust members of both the front and the rear bumpers yield outwardly respectively from the points 88 when the impact-receiving member 2 receives a shock near one end or the other.

It is obvious that may changes and variations and modifications may be made in departure from the particular description and showing of the accompanying drawing, in adapting the invention to varying condition and requirements of use and service, tomobile cl1assis',l100k bolts for engaging the Without departing from the true spirit of automobile lamp brackets and extending 10 the invention. through said securing members, and nuts Having thus disclosed my invention, I screwing'on the ends'of said bolts against claim and desire tosecure by Letters Patent: said securing members.
